My F250 required the tongue jack be down on the connected trailer or the rear jacks be touching the ground to prevent suspension sway when camped. The 5500 does not need the jacks for stability due to the stiffer spring pack, but we still drop the TC when we want to travel around an area without the TC on the rear (mostly in the wet months when we don't bring along seasonal vehicles to use as transportation). Our next trip, we are leaving the trailer at home - We will either drop the TC at camp and use the truck solo or we will haul the TC to all our daily stops. Having the electric jacks mounted and ready makes it an easy decision either way. I think if I had to crank manual jacks, it would be a rare occasion when I would be removing the TC.
